The 18-year-old has forced his way into the Under-21 side, starting again at Wolves on Monday, and is making good progress through the ranks.
Although he was born in Duffel in Belgium, his Brazilian background is apparent in his style as he is very comfortable on the ball. Marcos Pereira was a striker with Mechelen, Sint Truiden and Royal Antwerp and has helped his son adapt to the move from PSV Eindhoven.
"Everyone [in my family] is Brazilian - my father and my mother," he explained to ManUtd.com. "I was just born in Belgium.
"I've played at Under-17 and Under-18 level for Belgium but stopped this year because I think it's more important to develop here.
"My dad was a player in Belgium and that is why my family was there. He helped me with everything. All that I have learned, up to now, is from what he taught me.
"I think it helps a lot that he was a footballer. Sometimes my dad can say after a game what I did right and what I did wrong. We talk a lot. I can even watch it back on video with him as well now."
